Oku ukusetyenziswa kwamafutha ezihluthiyo - babe zingadityaniswa nezinye izinto eziyimfuneko ukuze umzimba, kwaye ixabiso eliphezulu. Inama ningumzimba akunjalo "tirhisa" ezinye iinjongo, ukuze yande.

Cholesterol - umhlobo okanye utshaba?

Enye into kukuba ubukho namafutha kumafa yabo cholesterol. Ezininzi eli gama inxulunyaniswa ukutyeba, kunye waphula iimpahla zentliziyo. Nangona kunjalo, kukho cholesterol "luncedo", nto leyo efunekayo ukuze siphile kwaye lukhutshwe umzimba wethu. Umbuzo ophakamayo, yintoni na ezityebileyo cholesterol kanye apho?

Malunga amafutha olun

Ekubeni sithetha ngayo amafutha, kubalulekile ukwazi ukuba amafutha olun nokuba zahluke njani eqhelekileyo. Trans amafutha akhiwa ngokugqithisela amaqamza hydrogen ngokusebenzisa ioli eqhelekileyo, ezifana nemifuno. Oku kwenzelwa ukunyusa ubomi bayo ezikhabhathini (kunye neemveliso yiyo leyo zenziwa kuyo) kunye ukuyenza imeko ezinzileyo. Owona mzekelo okuphawuleka a imajarini oluqhelekileyo. Ngelishwa, amafutha olun ziyingozi empilweni. Ukufumana emzimbeni womntu, banganeli kungqubana ukutya, kodwa kuchaphazela ngokungalunganga ukutya amanqatha, nto leyo kukwaphulwa inkqubo nethe insulin. Isiphumo - ukutyeba. Lahamba ukuzabalaza ifuthe elibi kwamafutha olun emadodeni - amanqanaba testosterone egazini labo kunciphisa kabukhali. Oku kukhokelela ukutyeba kwi "nemazi" uhlobo ngamanqatha efakwe kwi esinqeni, ezinqeni namabele. Ukongeza, ngokuphawulekayo kunciphise umsebenzi erectile, izihlunu zomzimba SAG kwaye ubhitye yayo. Ngoko ke, ukuze zonke iziphumo ezingalunganga ezinokwenzeka, kubalulekile ukwazi ukuba amafutha yothutho kunye amafutha ifumile.

Trans amafutha afumaneka imajarini, hayi nje kuphela, ukuba inokufumaneka kuhlanganiselo chips zamazambane, iikuki kunye nezinye "bathenga" ehla, pizza ekhenkciweyo, kunye nezinye izinto ezininzi. Xa inani yezityebileyo besukelana malunga-50%, ekubeni abaninzi kubo zilungiselelwa usebenzisa amafutha hydrogenated. Ngokomzekelo, enye inxalenye chips malunga ne-14 iigrem yamanqatha yothutho kwindawo inyanda encinane yeetshipsi - 3 grams nganye ekukhonzeni yenkuku eqhotsiweyo - 7 grams nganye ukukhonza isidlo sakusasa elomileyo - 2 grams. Ukuze eyonakalisa impilo yabo, kwanele ukuba kusetyenziswe umhla grams ngaphezulu kwe-4 okunamafutha trans.

Amafutha, iiprotheni kunye carbohydrate - iqela elinye

Yintoni amafutha, iiprotheni kanye carbohydrate? Le yenye "iqela" zezinto ukusuka kwindawo eneji lwembono usenokuba ukutshintshwa omnye. Noko ke, ukuba umzimba ihlawula yokunqongophala carbohydrate protein kunye namanqatha, uya kufuneka bachithe amandla kratya ukugaya kubo. Kodwa khumbula ukuba iiproteni - ingumthombo acid kubalulekile kunye namanqatha - umthombo asidi kubalulekile ezinamanqatha, ngoko kule nkalo kuba ayibuyiselwa. Eyona nto inzima xa umzimba ukungabi protein.

Protein - isakhiwo ezibonakalayo ukuze umzimba. Siqulathe uthotho asidi acid, 9 apho kuza kuphela ukutya kunye emzimbeni ayikwazi kuhlanganiswa. ukutya kwezilwanyana buneprotini ngaphezu izityalo kunye digestibility ye iiproteni yi-90%, lo gama iiproteni yemifuno imvelaphi wendele% kuphela 65.

Yintoni ngamanqatha? Le reserve amandla komzimba. Kwaye ukuba kukho ukunqongophala kubo, iiproteni baqala iba ngenkuthalo - ukusilela kwamadlala kwenzeka emzimbeni, ngawe ulusu, kunciphise ukumelana semithambo, kukho iingxaki ekugayeni.

Wekhabohayidreyiti lo mthombo wamandla ingqondo, lo gama izihlunu zomzimba ukufumana amandla ngokuguqula amafutha. Ngokuqhelekileyo, carbohydrate zahlulwe zibe alula nanzima. I luncedo kakhulu zithathwa carbohydrate ezintsonkothileyo okanye polysaccharides. abaphumeleli yabo kunokubangela ukuhla protein, kwakunye kwemfuneko ikhokelela ubunzima ngokugqithiseleyo. Ngoko ke, kubalulekile ukuba ufumane indawo ephakathi.
